Hey George, how many Boost Levels you've got available in Transaction Booster with BIOS v0404 ? { I don't have the P5K here, I brought the p5k3 with me only }
Because with the latest BIOS for the P5K3D ( v0601 ) there are new Boost Levels ( 0,1,2,3 ) Haven't tested them yet ( oh, they also added FSB Strap Control )
Keep your eyes out for a new P5K Deluxe BIOS @ Asus's .tw FTP
